Adafruit RFM69HCW 915MHz Transceiver Radio Module

Sending data over long distances can feel like magic, but with these radio modules, you'll master the trick. Unlike WiFi or Bluetooth, which use 2.4GHz, these modules operate on lower frequencies such as 433 or 900 MHz, allowing data to travel much farther, though at reduced speeds.

The modules easily connect without needing to pair or worry about complex connections, making communication seamless. Just send data, and any module on the same frequency and encryption key will receive it. They are equipped with packetization, error correction, and auto-retransmit features, conserving power that would otherwise be consumed in maintaining links.

Perfect for use with Arduinos or other microcontrollers, they support projects like sensor node networks or data transmission over considerable distances. This version works on the 900 MHz band, allowing for either 868MHz or 915MHz transmission upon software tuning, making it versatile for different regional requirements. We also offer a 433 MHz version.

These are +20dBm FSK packet radios with encryption and range capabilities up to 5km with the right antennas. Specs include: SPI interface, 13 to 20 dBm power output, and multilevel current draw optimized for different power levels. Form multipoint networks effortlessly and enjoy security with AES-128 encryption.

This product is sold individually, ensuring compatibility only with radios of the same part number. Assembly is required as it is not pre-mounted on a PCB, providing flexibility in application but necessitating personal soldering or automated processes. This module is a core component in all related RFM69 900MHz products.
